ISA-389G Panel WB702E

The ISA-389G universal auxiliary device can perform functions such as three-phase operation, voltage paralleling, and voltage switching. It can also accommodate a repeating module to achieve signal or contact repeating functions. Depending on functional requirements, the device can be equipped with any of the following eight universal function modules.

It works in coordination with various protection devices to perform functions like trip and close operations, voltage switching, voltage paralleling, and repeating. Each module operates independently without mutual interference. The device can be configured with up to 5 modules, and the installation order is flexible for convenient use.

Features:

· The device adopts a standard 4U (full-layer) chassis with a modular structure and plug-in backplane wiring. It offers high reliability and flexible operation.

· The three-phase operation module includes a pressure blocking circuit, three sets of position signal outputs, control circuit break and fault alarm outputs, and an anti-jump circuit that can be disabled via external terminal shorting.

· The voltage paralleling circuit supports up to 10 voltage paralleling functions.

· The voltage switching circuit supports up to 8 voltage switching functions. If more than 8 voltage inputs require switching, multiple voltage switching modules can be used.

· The device uses imported fully sealed, high-impedance, low-power consumption relays, significantly reducing power consumption and heat generation.

· It can adapt to various trip and close holding currents automatically.
